You are to design, write, assemble, and simulate an assembly language program which will calculate the

factorial N$!$ of an unsigned $1-$byte number N$.$

The factorial of N is defined as: $0!=1$ and N$!=1*2*3*..*($N$-1)*$ N$,$ for N $>0$

For example, for N$=8,$ N$!=40320=$ $$9$D$80.$

One way to calculate N$!$ is iteratively in N steps:

$1.$ calculate $1!$

$2.$ calculate $2!=1!*2$

$3.$ calculate $3!=2!*3$

$4.$ calculate $4!=3!*4$

$...$

N$.$ calculate N$!=($N$-1)!*$N

For this lab, N is a $1$ byte number, while the result $($N$!)$ is stored as a $2-$byte number in NFAC in BIG

ENDIAN format

YOU MUST FOLLOW THE C PROGRAM BELOW $1$ TO $1,$ DO NOT CHANGE. my current assmebly program isn't calculating correctly, when N is set to $8$ it says the NFAC is $$0$D$80$ which is incorrect. So please help me$.$ And if you could change my program as little as possible and DO NOT go against the psudocode as it must be $1$ to $1$
